Specification of Letters Patent.

Patented. J an. 21, 1913.

Application filed November .18, 1912. Serial No. 732,118.

To all whom it may concern:

Be it known that I, JAMEs K. BURLEIGH, a citizen of the United States,residing at 508 Clinton avenue, Kalamazoo, Michigan, have inventedcertain new and useful Improvements in Signs, of which the following isa specification.

This invention relates to improvements in signs. e

The main objects of this invention are, first, to provide in a sign inwhich the sign indicia or characters are formed of lenses, an improvedmeans for securing the lenses.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred GlIIbOdlr ment of my invention isclearly illustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a front detail view of a sign structure embodying thefeatures of my invention, a single letter only being illustrated, theparts being shown mainly in conventional form. Fig. II is a detailsection through the face plate on a line corresponding to line 22 ofFig. 1, the lens being shown in full lines. Fig. III is a transversesection through the shank of the lens on a line corresponding to line3-3 of Fig. II. Fig. IV is a detail section on a line corresponding toline 5-5 of Fig. III. Fig. V is a section through the lens on a linecorresponding to line 55 of Fig. III. Fig. VI is adetail front view ofthe face plate showing one of the lens openings therein.

In the drawing similar reference characters refer to similar partsthroughout the casing structure is shown in the patent to Bambeck,#1,030,449, of June 25, 1912, and I preferably embody my improvements ina sign of the character there indicated.

The lenses 2 are arranged in the face plate in groups to form the signindicia or characters or to produce a suitable design or outline. Thelens 2 is preferably convex and provided with a shoulder 3 arrangedagainst the face plate when the lens is seated and with an inwardlyprojecting short tapered shank 4.

The diameter of the shank at the base of the shoulder is such that itfits closely in the openings 5 in the face plate it being a turning fittherein. The opening 5 is circular and is formed with inwardlyprojecting rearwardly deflected lugs 6 on its edges. 1

The lens shank 4 is provided with peripheral grooves 7 with notches 8 atone end through which the lugs may be introduced into the grooves. Thegrooves are provided with inclined or cam portions 9 which coactwith thelugs to draw the shoulder against the face plate when the lens isturned. The grooves are of such depth that the inner ends of the lugsengage the lower inner corners of the groove as shown in Fig. IV.

At the ends of the grooves are locking notches 10 into which the lugs 6are forced by the inclined walls 11 above the notches.

Besides positively forcing the lugs into the locking notches, theseinclined walls 11 support lugs so that the clamping tension is notloosened by the dropping of the lugs into the locking notches.

With the parts thus arranged, the shoulders of the lenses are clampedfirmly against the face plate making a very tight joint and further. thelenses cannot rattle or drop out. The lenses are readily molded and theface plates with the openings easily formed and the parts may be veryrapidly and easily assembled. Further there is litt-le danger of thelenses being broken in as-- sembling.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A sign comprising a face plate of sheetmetal having a substantially circular opening and provided with aplurality of rearwardly deflected lugs projecting from the edge of theopening; and a lens provided with a shoulder arranged to contact with aside of said face plate and with a shank, the

shank at the base of the shoulder being a turning fit in said openingand being provided with peripheral lug engaging grooves and notchesthrough which lugs may be ing and provided with a pluralityof rearwardlydeflected lugs projecting from the edge of the opening; and a lensprovided with a shoulder arranged to contact with a side of said faceplate and with a shank, the shank at the base of the shoulder being aturning fit in said opening and-being provided with peripheral lugengaging grooves and notches through which lugs may be entered, thegrooves being provided with A cam portions coacting with said lugs todraw the shoulder against the face plate, there being lug lockingnotches at the inner ends of said cam portions.

3. A sign comprisin'ga face plate of sheet metal having a substantiallvcircular opening and provided with a plurality of rearwardly deflectedlugs projecting from the edge of the opening; and a lens provided with ashoulder arranged to contact with a side'of said face plate and with ashank, the

. shank at the base of the shoulder being a turningfit in said openingand being provided with peripheral lug engaging grooves 'ilnd notchesthrough which lugs may be entered, the grooves being provided with camport-ions coacting with said lugs to draw the shoulder against the faceplate, the inner walls of the groove being inclined at saidlockingl'notches whereby the lugs are forced into the notches as thelens is turned to seat the same.

4. A sign comprising a face plate of sheet.

metal havinga substantially circular opening and provided with aplurality of rear wardly deflected lugs projecting from the edge of theopening; and a lens provided with a shoulder arranged to contact with aside of said face plate and with a shank, the

shank being provided with peripheral lug engaging members having camportions 00- acting with said lugs to draw the shoulder against the faceplate, there being lug locking notches at the inner ends of'said camportions and inclined walls over said notches whereby the lugs areforced into the notches as the lens is turned to seat the same.

5. A sign comprising a face plate of sheet metal having a substantiallycircular opening .and provided with a plurality of rearwardly deflectedlugs projecting from the edge of the opening; and a lens provided with ashoulder arranged to ,contact with a side of said face plate and with ashank, the

shank being provided with peripheral lug engaging members having camportions coacting .with said lugs to draw the shoulder against the faceplate, there being lug locking notches at the inner ends of said camportions.

6. A sign .comprising a face plate of sheet metal having a substantiallycircular opening and provided with a plurality of rearwardly deflectedlugs projecting from the edge of the opening, and a lens provided with ashoulder arranged to contact with the side of said face plate and with ashank, the shank being provided with lug engaging notches havinginclined inner walls whereby.

the lugs are caused to seat in the bottoms of the notches.

7. A sign comprising a face plate of sheet metal having a substantiallycircular opening and provided with a plurality of rearwardly'defiectedlugs projecting from the edge of the opening; and a lens-prov1ded with ashoulder arranged to contact with. a side of said face; plate and with ashank, the shank at the base of the shoulder being a turning fit in'-said opei ing and being pro-- vided with peripheral lugengaging-grooves and notches through which lugs may be entered, thegrooves being provided with cam portions coacting with said lugs to drawthe shoulder against the face plate.

In. witness whereof, I have hereunto set my hand and seal in thepresence of two witnesses.
